Boats and Streams - Aptitude Questions and Answers

A giant container ship the length of four football pitches has become wedged across Egypt's Suez Canal, blocking one of the world's busiest trade routes. Dozens of vessels are stuck, waiting for rescue boats to free the m-long 1,ft ship, which was knocked off course by strong winds. Egypt has reopened the canal's older channel to divert some traffic until the grounded ship can move.

The Ever Given, registered in Panama and operated by boat and stream problems in malayalam 85 shipping company Evergreen, was bound for the port city of Rotterdam in the Netherlands from China and was passing northwards through the canal on its way to the Mediterranean. Thetonne ship, built in and operated by Taiwanese transport company Evergreen Marine, ran aground and became lodged sideways across the waterway at about local time GMT on Tuesday.

At m long and 59m wide, the ship has blocked the path of other vessels which are now trapped in lines in both directions. The company that manages boat and stream problems in malayalam 85 container ship, Bernhard Schulte Shipmanagement BSMhas denied earlier reports that the ship had already been partially refloated. In a statementit said its "immediate priorities are to safely re-float the vessel and for marine traffic in the Suez Canal to safely resume".

Reuters, quoting local sources, says there are at least 30 ships blocked to the north of the Ever Given, and three to the south. Evergreen Marine said the ship boat and stream problems in malayalam 85 "suspected of being hit by a sudden strong wind, causing the hull to deviate BSM confirmed on Wednesday that all crew were "safe and accounted for", with no reports of injuries. Eight tug boats are boat and stream problems in malayalam 85 to refloat the ship, and diggers on the ground have been removing sand from where it is wedged into the side of the canal bank.

Dr Sal Mercogliano, a maritime historian based in the US state of North Carolina, told the BBC that incidents such as this were rare, but could have "huge ramifications for global trade". The Kpler energy intelligence service said boat and stream problems in malayalam 85 more than 20 oil tankers carrying crude and refined products were affected by the jam. Julianna Cona, who says she is on board another ship located directly behind the Ever Given, wrote on Instagram : "Ship in front of us ran aground while going through the canal and is now stuck sideways looks like we might be here for a little bit The Suez Canal is an artery of world trade, connecting the Mediterranean with the Red Sea, and providing an avenue for vessels to pass between Asia and the Middle East and Europe.

The main alternative, a passage round the Cape of Good Hope at the southern tip of Africa, takes considerably longer. It is particularly important as an avenue for oil and liquified natural gas, enabling shipments to get from the Middle East to Europe. The nightmare scenario, then, is for this crucial route to be blocked - which is exactly what has now happened with the stranding of the Ever Given.

The question now is how long the route remains impassable, as a long delay would create serious problems for shippers, delaying consignments of goods and fuel. On this occasion, reports suggest traffic could be flowing again relatively quickly, in which case the impact will be limited, although there has been a rise in the oil price.

But the incident has shown what can go wrong when the new generation of ultra-large vessels like the Ever Given have to pass through the relatively tight confines of the canal.

Although parts of it were expanded as part of a major modernisation programme boat and stream problems in malayalam 85 the middle of the last decade, it remains tricky to navigate - and accidents can happen. The ship has the capacity to carry 20, ft shipping containers, according to Reuters news agency. Nearly 19, ships passed through the canal inaccording to the Suez Canal Authority - an average of Ina Japanese container vessel blocked the canal after it ran aground following reported mechanical issues.

The Egyptian authorities deployed tug boats and the ship was refloated within hours. The canal is km miles long and incorporates three natural lakes. InEgypt's government opened a major expansion of the canal that deepened the main waterway and provided ships with a 35km 22 mile channel parallel to it. Why the Suez Canal matters - in 60 secs. Egypt opens Suez Canal expansion. The blockage sent oil prices climbing on international markets.

What;s the serial? Mercury60 Seaman Apprentice. Joined Apr 1, Messages Re: Mercury Outboard no pee hole discharge Pee hole discharge? Sure you don't want to see a doctor? I had to. I've dealt with and am dealing with this right now. Chances are your impeller is toast or there is an obstruction somewhere.

Having a water pressure and temp gauge will help tell you exactly whats going on. Also, if you can do it You will then be able to simulate real world conditions and water pressures. Re: Mercury Outboard no pee hole discharge It's a Merc 60hp 2-stroke. From pretty much everything I've read, this is not normal. The weird part is the guy I bought it from claims it has never "peed" he may just be mistaken, or lying, but I believe him.

And you don't have to see a doctor til it burns right? Re: Mercury Outboard no pee hole discharge vparker said:. Re: Mercury Outboard no pee hole discharge Chances are this guy is lying to you.

My bet would be that the impellar burned up fairly recently. The motor wouldn;t last long at all with no cooling capabilities ie;toasted impellar. A motor with no impellar could burn up in just seconds at WOT. Let's keep fingers crossed that all you're dealing with is a clogged discharge hose. If you don;t find any sign of cloggage, check the compression also with fingers crossed and pray that the needle points anywhere from the low 's to about 'ish with little variation between cylinders.

If compression is good, pull the LU and get that water pump serviced. As previously mentioned, it's good to replace the impellar and inspect all the LU seals prior to running the motor again. By all means, DON'T run the motor until you get this figured out. Joined Mar 31, Messages 4. Re: Mercury Outboard no pee hole discharge I just replaced my impeller last night. After I got everything back together and fired it up there was water coming out of the exhaust but not out of the tell tale.

Once I pulled it back off I realized I had not got the water tube lined up right and it was not in the port to Boat And Stream Problems In Malayalam University send water through the block. Once I got it lined up right it worked great. My point is it sounds like the pump may be working if there is water flowing, it just isn't flowing where it is supposed to.

It was a little piece from the broken water pump impeller. Just a quick blow with the air compressor and it came right out. Pumps like a charm now! Good luck! Marty Niner Seaman Apprentice. Joined Aug 6, Messages Re: Mercury Outboard no pee hole discharge I have noticed that Mercs "pee" alot less than say Johnsons or Evinrudes better bladder control I guess , but if there is water coming out of the prop hub exhaust would it not mean that water is flowing throught the block?

My Merc barely pees when it is idling on the muffs too, but water does come out of the prob hub?? Joined Aug 25, Messages Re: Mercury Outboard no pee hole discharge Do as the guys have mentioned before and check for obstruction in the pee-hole.

Also when you have had the engine running, how hot is it getting. All of my engines get warm but you can leave your hand on them, and all of my Mercs. Do not run the boat for more than a couple of minutes without seeing the peehole.

Your pump may be working correctly, but we need to see it coming out of the pee hole to know that it is pumping and that it is geting enough pressure. Re: Mercury Outboard no pee hole discharge Re: Mercury Boat And Stream Problems In Malayalam App Outboard no pee hole discharge I hate the muffs. I much prefer using a big clean trash barrel. If in doubt just find a trash barrel big enough for your motor to fit in and fill it up. Motorboat problems such as these are typically accompanied by three separate questions:.

The first of these three questions was answered above; the resultant velocity of the boat can be determined using the Pythagorean theorem magnitude and a trigonometric function direction.

The second and third of these questions can be answered using the average speed equation and a lot of logic. The solution to the first question has already been shown in the above discussion.

We will start in on the second question. The river is meters wide. That is, the distance from shore to shore as measured straight across the river is 80 meters.

The time to cross this meter wide Boat And Stream Problems In Malayalam Us river can be determined by rearranging and substituting into the average speed equation. The distance of 80 m can be substituted into the numerator. But what about the denominator?

What value should be used for average speed? With what average speed is the boat traversing the 80 meter wide river? Most students want to use the resultant velocity in the equation since that is the actual velocity of the boat with respect to the shore. And the diagonal distance across the river is not known in this case.

If one knew the distance C in the diagram below, then the average speed C could be used to calculate the time to reach the opposite shore. Similarly, if one knew the distance B in the diagram below, then the average speed B could be used to calculate the time to reach the opposite shore.

And finally, if one knew the distance A in the diagram below, then the average speed A could be used to calculate the time to reach the opposite shore. It requires 20 s for the boat to travel across the river. During this 20 s of crossing the river, the boat also drifts downstream. Part c of the problem asks "What distance downstream does the boat reach the opposite shore? And once more, the question arises, which one of the three average speed values must be used in the equation to calculate the distance downstream?

The distance downstream corresponds to Distance B on the above diagram. The speed at which the boat covers this distance corresponds to Average Speed B on the diagram above i. The mathematics of the above problem is no more difficult than dividing or multiplying two numerical quantities by each other. The mathematics is easy! The difficulty of the problem is conceptual in nature; the difficulty lies in deciding which numbers to use in the equations.

That decision emerges from one's conceptual understanding or unfortunately, one's misunderstanding of the complex motion that is occurring. The motion of the riverboat can be divided into two simultaneous parts - a motion in the direction straight across the river and a motion in the downstream direction. These two parts or components of the motion occur simultaneously for the same time duration which was 20 seconds in the above problem.

The decision as to which velocity value or distance value to use in the equation must be consistent with the diagram above. The boat's motor is what carries the boat across the river the Distance A Boat And Stream Problems In Malayalam Office ; and so any calculation involving the Distance A must involve the speed value labeled as Speed A the boat speed relative to the water. Similarly, it is the current of the river that carries the boat downstream for the Distance B ; and so any calculation involving the Distance B must involve the speed value labeled as Speed B the river speed.

Together, these two parts or components add up to give the resulting motion of the boat. That is, the across-the-river component of displacement adds to the downstream displacement to equal the resulting displacement. And likewise, the boat velocity across the river adds to the river velocity down the river to equal the resulting velocity.

Now to illustra te an important point, let's try a second example problem that is similar to the first example problem. Make an attempt to answer the three questions and then click the button to c heck your answer. The resultant velocity can be found using the Pythagorean theorem.

It is. An import ant concept emerges from the analysis of the two example problems above. In fact, the current velocity itself has no effect upon the time required for a boat to cross the river. The river moves downstream parallel to the banks of the river. As such, there is no way that the current is capable of assisting a boat in crossing a river.

While the increased current may affect the resultant velocity - making the boat travel with a greater speed with respect to an observer on the ground - it does not increase the speed in the direction across the river.

The component of the resultant velocity that is increased is the component that is in a direction pointing down the river. It is often said that "perpendicular components of motion are independent of each other. The time to cross the river is dependent upon the velocity at which the boat crosses the river. It is only the component of motion directed across the river i.

The component of motion perpendicular to this direction - the current velocity - only affects the distance that the boat travels down the river. This concept of perpendicular components of motion will be investigated in more detail in the next part of Lesson 1. Determine the resultant velocity of the plane magnitude only if it encounters a. If the width of the river is 80 meters wide, then how much time does it take the boat to travel shore to shore?
